WATCH ABOVE: Asked about a letter from frontline workers at Lakeridge Hospital who say they're having to extend the use of personal protective equipment (PPE), Ontario Health Minister Christine Elliott said the province has an "adequate" supply of PPEs and is working to obtain more.

A health-care worker at a long-term care home in Markham has tested positive for the novel coronavirus.

The Service Employees International Union (SEIU) said the frontline worker contracted the disease after a resident in the home was confirmed to have had the virus last week.

SEIU said additional workers who may have been exposed are waiting for their test results.
